| Resumo | A study of the shaping of the seafloor morphology on the Brazilian continental shelf probably caused by abrupt climatic changes in the beginning of the Holocene is being made with the use of TM-LANDSAT 5 Data. Special emphasis is given on analysis of an ancient shoreface at 20m depth, correlated with abrupt global climate change between 8000-10000 B.P., and on mapping of sedimentary deposits, which were first described by TM-LANDSAT imagery. The transport of a quatz sand deposit by unidirectional currents through time will also be described, together with the description of presentday active sandwave fields at the 20m isobath. Two images were used (path/row 214/64 and 215/63, sites at northeast Brazilian coast), corresponding to two dates: 1984 and 1989. Geometric correction, filter application (striping minimization)and contrast enhancement were automatically performed. A gray level slicing image classification technique was conducted to obtain the preliminary bottom composition chart. Field work included samples collection from the soft bottom and beachrock reefs, in areas selected by examination of the final image products. A Geographical Information System was used to insert bathymetric and geological data into the analysis system. The GIS products were registered with the thematic images. The association of TM data, GIS products and field data helped in the preliminary sedimentological characterization of the area. Five bottom types were characterized: fine and coarse sand, coral/algal bioherms, beachrock reefs and foliaceous algal fields. A comparison between '84 and '89 images permit us to analyze the migration pattern of the sand waves, along a five-year period. |
